Any info or refs on this pic?

Hi!

I scanned these pics from 'Fighting Jets of WW2' by Jeffrey Ethell and
Albert Price (which I thoroughly recommend btw)

http://www.johnmullen.org.uk/temp/262.jpg

The picture caption mentions that German helicopters were carried aboard HMS
Reaper and the photo credits the Smithsonian, whose site mentions that most
of the a/c ended up in their collection after evaluation in the USA.

What I have been totally unable to find is any other reference to the
helicopters found. Pictures or any other info would be very greatly
appreciated.

Thanks for any help you can give.

John
